Abstract: 602,730. Cone and disc brakes. FIRESTONE TIRE & RUBBER CO. June 29, 1944, No. 12402. Convention date, May 29, 1943. [Class 103 (i)] A disc brake, particularly for aircraft land wheels comprises two series of conical discs alternately splined to the wheel and to the fixed axle and forced together by a corrugated diaphragm deflected by fluid pressure. Cooling is effected by the circulation of air about a housing for the brake. As shown, conical discs 50, 51 are alternately splined to the wheel and to the fixed axle 13 by toothed members 54, 56, the member 54 being secured to the wall 17 of a brake housing 16, 17 which is closed by a plate 28 fixed to the axle. The sides of the teeth of the member 54 are parallel and those of the teeth of the discs 50 converge towards the centre, Fig. 3, to permit of heat expansion of the discs without binding, while avoiding lost-motion between the discs and the member 54. The teeth of the member 56 and of the discs 51 are of involute form to prevent concentration of stress at the root of the teeth. Normal separation of the discs is effected by a number of circumferentially-spaced helical springs 66 which abut on a stop ring 68. The fluid-pressure actuating device comprises a corrugated diaphragm in two annular parts 35, 36 secured at their adjacent edges to a ring 37 and at their other edges to flanges 30, 29 on the closure plate 28. The ring 37 is positioned by two series of sector-shaped plates 38, 39 which engage in circumferential grooves in the ring and in the flanges 29, 30. When the diaphragm is deflected by admission of pressure fluid to the space between it and .the plate 28 through passage 43, the ring 37 moves axially to apply pressure to the discs by its engagement with a pressure disc 60. Cooling air is drawn into the wheel through an opening in the outer closure disc of the wheel by rotation of the webs 75 and after circulating about the housing 17, 18 escapes through ports A.
